Humans or Inhumans – Oz to kill 650000 Camels

What to say of the report. How cruel can humans be. Can there be any other creature on earth which is more cruel than man? Even the jungle rule is better. Animals kill each other only for food. It is only humans who kill for either pleasure or because they feel some other life forms are causing problem to them.Is it a wonder that humans are the ones most prone to disease of the body and of mind?
